Transitional–turbulent spots bridge the deterministic laminar state with the stochastic
turbulent state and affect the transition zone length in engineering flows. Turbulent spot …

This article reviews recent advances in the understanding of turbulent flows of non-ideal
gases through the use of high-fidelity direct and large eddy simulations. In particular, the …

Strong interactions of shock waves with boundary layers lead to flow separations and
enhanced heat transfer rates. When the approaching boundary layer is hypersonic and …

The linear instability and breakdown to turbulence induced by an isolated roughness
element in a boundary layer at Mach roughness heights from the roughness trailing edge …

To investigate the pressure-fluctuation field beneath turbulent spots in a hypersonic
boundary layer, a study was conducted on the nozzle wall of the Boeing/AFOSR Mach-6 …

Exascale computing will feature novel and potentially disruptive hardware architectures.
Exploiting these to their full potential is non-trivial. Numerical modelling frameworks …

High-resolution direct numerical simulations (DNS) were carried out to investigate the
nonlinear breakdown process of a three-dimensional wave packet initiated by a short …

Wall cooling has substantial qualitative and quantitative effects on the development of
instabilities and subsequent transition processes in hypersonic boundary layers (HBLs). A …

The freestream turbulence-induced transition of a dense-gas boundary layer past a thick
leading edge representative of turbine blades is investigated with large-eddy simulations …

Scramjet engines, also known as supersonic combustion ramjet engines, are frequently
regarded as a compelling alternative for launching payloads into Earth's orbit. These air …
